How To Use Atlasly Inside Claude, ChatGPT, and Other AI Assistants
Connect Atlasly’s hosted MCP endpoint in a supported Claude or ChatGPT client, verify discovered tools and distinguish public checks from account-linked operations.

Quick answer
Atlasly’s hosted endpoint is https://mcp.atlasly.app/mcp. Add it through your client’s supported custom connector or app setup, then inspect the tools available to your account and run a bounded site question. Setup and permissions vary by client and plan; public evidence checks and account-linked operations have different access requirements.
Connecting Atlasly can make its available site-review tools accessible within a compatible assistant. It does not give every client every Atlasly feature or guarantee the correctness of a planning answer. Confirm the current client setup, inspect discovery and review the sources in a first result.
The endpoint and public/account-linked distinction were checked against Atlasly’s published server card and content contracts. Client guidance was reviewed on 12 September 2026; this is not an end-to-end compatibility certification for every plan or device.
Confirm your client supports the connection
Use Atlasly’s connection page and the client’s current official instructions. The hosted URL is https://mcp.atlasly.app/mcp. This remote connection differs from installing a local desktop server.
The repository’s public server card currently lists 27 public tools and five account-linked operations. Those counts are a dated description, not a promise that your client exposes every tool or that every request succeeds. Inspect the discovered list, input requirements and access information.
Connect in Claude
Follow Claude’s custom remote connector guide. Add a custom connector from the supported connector settings, name it Atlasly and enter the hosted URL. Workspace permissions and the current client control availability.
After connecting, start a conversation with the connector enabled and ask a bounded question such as “Using Atlasly, review available flood evidence for this site and identify missing sources.” Check that an actual tool result and source links are returned. Do not assume a slash command is supported in every interface.
Connect in ChatGPT
Use OpenAI’s developer-mode and MCP app guidance. The documented full MCP workflow is on ChatGPT web for eligible Business and Enterprise/Edu accounts with the appropriate permissions; the page distinguishes Pro read/fetch access. Do not equate this with a Custom GPT action or promise availability on every Plus account.
An authorised user creates the custom app, supplies the Atlasly endpoint and authentication configuration, scans the tools and tests the draft. Workspace publication and access follow the administrator’s controls. Follow the current official flow when labels change.
Keep public checks separate from account-linked actions
Public tools are intended to support an initial review without an Atlasly account, subject to request limits and service availability. Creating a project, running a site package, checking its job, generating a saved brief and enabling Site Watch are the account-linked operations listed in the server card.
Follow the offered authorisation flow when needed and inspect the requested permissions. Do not assume consent is permanent or that credentials can never expire. Client-plan eligibility, Atlasly account access and export entitlement are separate questions.
Evaluate the first answer and export handoff
Ask for the source, date, boundary used and missing layers. Verify material planning and environmental conclusions against the underlying record. A successful connection does not establish nationwide completeness.
The public tool list does not establish direct CAD-file delivery in every chat. Where a response provides a link into Atlasly, check the available export format and entitlement in the app. Do not promise that a signed file appears in every answer or that AutoCAD opens automatically. Read the methodology and limits before relying on the evidence.
Illustrative example
Illustrative scenario: A planner asks for source links alongside a site summary, then opens the current policy and designation records. An unverified paragraph reference stays out of the client advice until checked.
Frequently asked
What endpoint should I use?
Use https://mcp.atlasly.app/mcp through your supported client’s custom remote connector or app setup.
Do public checks require an Atlasly account?
They are intended for anonymous public access, subject to request limits. Account-linked operations and export entitlements are separate.
Does this work identically in every assistant?
No. Client capabilities, account plans, permissions and interfaces vary. Confirm discovery and test the intended workflow.
Can I export a DXF automatically in any chat?
This guide does not establish universal direct file delivery. Follow the supported export handoff in Atlasly and check the resulting file.
Conclusion
Connect through the current official client workflow, inspect available tools and test a focused evidence question. Treat successful setup and verified site evidence as separate checks.
